Ragazzi sulla base di questo studio sembra che il piroctone olamine sia addirittura meglio del ketoconazolo come coadiuvante nella lotta all'aga. Anzi sarebbe ancora meglio visto che è una sostanza naturale(e meno aggressiva) e non una molecola sintetica come il keto. Sul forum però ho letto pareri positivi solo sull'utilizzo del nizoral nella lotta alla calvizie. Questo studio è attendibile? Qualcuno di voi ha provato il piroctone x periodi prolungati? Sapreste indicarmi la marca di uno shampoo con piroctone all'1%?
Stavo pensando di alternarlo al nizoral...sarebbe troppo? Meglio puntare su uno solo dei due attivi ed alternarlo con un delicato?
Un'ultima domanda: va davvero bene comunque utilizzare uno shampoo come il nizoral SOLO per la lotta all'aga non soffrendo di dermatite seborroica?
Grazie a tutti

Nudging hair shedding by antidandruff shampoos. A comparison of 1% ketoconazole, 1% piroctone olamine and 1% zinc pyrithione formulations.
International Journal of Cosmetic Science Volume 24, Issue 5, Page 249-256, Oct 2002
Synopsis
Hair shedding and hair thinning have been reported to be affected by dandruff and seborrhoeic dermatitis. The present study was conducted in 150 men presenting with telogen effluvium related to androgenic alopecia associated with dandruff. They were randomly allocated to three groups receiving each one of the three shampoos in the market containing either 1% ketoconazole (KTZ), 1% piroctone olamine (PTO) or 1% zinc pyrithione (ZPT). Shampoos had to be used 23 times a week for 6 months. Hair shedding during shampoo was evaluated semiquantitatively. Hair density on the vertex was evaluated on photographs using a Dermaphot. Trichograms were used for determining the anagen hair percentage and the mean proximal hair shaft diameter using computerized image analysis. The sebum excretion rate (SER, g cm2 h1) was also measured using a Sebumeter®.
The three treatments cleared pruritus and dandruff rapidly. At end point, hair density was unchanged, although hair shedding was decreased (KTZ: -17.3%, PTO: -16.5%, ZPT: -10.1%) and the anagen hair percentage was increased (KTZ: 4.9%, PTO: 7.9%, ZPT: 6.8%). The effect on the mean hair shaft diameter was contrasted between the three groups of volunteers (KTZ: 5.4%, PTO: 7.7%, ZPT: -2.2%). In conclusion, telogen effluvium was controlled by KTZ, PTO and ZPT
